Experimentally validated theory for the mixing of granular materials. The project aims to develop better mixing theories to support industrial applications. Effective mixing of granular materials such as aggregates in building industry and stockpiles in mineral processing is important for creating homogeneous products, yet industrial mixers lack scientific design and operate with no control of mixture quality.

The project aims to develop better mixing theories to support industrial applications. Effective mixing of granular materials such as aggregates in building industry and stockpiles in mineral processing is important for creating homogeneous products, yet industrial mixers lack scientific design and operate with no control of mixture quality. The project aims to establish a new general continuum mixing theory, which will be validated against X-ray measurements of grain motions within small mixers. By describing the theory using an accurate computational method, the simulations of these mixers will be scalable, and would help deliver predictions for particle mixing in much larger operations. Other expected outcomes are to control mixture quality and reduce industry reliance on costly and time-consuming trial-and-error experiments.Read moreRead less

Mudstones as methane sources: gas production from coal seam interburden. Carbonaceous mudstones associated with coal measures already exploited for gas present an attractive reservoir of methane. This project seeks to provide methods for accessing this gas. Mudstone associated with coal seam gas developments are very extensive and gas quantities may exceed even that in the coal itself. Further infrastructure and access permits are already in place for coal seam gas recovery. Unlike shale, which ....Mudstones as methane sources: gas production from coal seam interburden. Carbonaceous mudstones associated with coal measures already exploited for gas present an attractive reservoir of methane. This project seeks to provide methods for accessing this gas. Mudstone associated with coal seam gas developments are very extensive and gas quantities may exceed even that in the coal itself. Further infrastructure and access permits are already in place for coal seam gas recovery. Unlike shale, which is fissile, mudstone is much softer, more malleable and plastic, and consequently will respond abnormally to hydraulic fracturing and propping, so new methods proposed to be developed in this project are needed for stimulation.Read moreRead less
